Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] see Figure 5-Figure 12 , a new type of thin coal seam shearer "reversed buckle" type walking device, mainly including shield 1, guide shoe 2, pressure plate 3, bolt 4, gland 5, pin rail 6, long spline shaft-7 , Bearing seat 8, walking wheel 9, etc.

[0034] The traveling wheel 9 is directly connected to the end of the long spline shaft and meshes with the pin rail 6 to reduce the height of the machine surface and increase the coal passing space; the shield 1 is installed on the traction shell through high-strength hydraulic bolts, and the shield 1 There is a boss 1a used to support the guide shoe 2, the boss 1a is in the shape of a circular arc, and the arc gap is downward; the guide shoe 2 has a ring support ring 2a, and the ring support ring 2a is hung on the boss 1a ; The boss 1a is used as the rotation axis of the guide shoe, so t...

Abstract

The invention relates to a traveling device of a coal mining machine for thin coal seams, particularly relates to a reversely-fastening type traveling device of the coal mining machine for the thin coal seams and belongs to the technical field of traveling devices of the coal mining machines. The traveling device is characterized by comprising a protective cover (1), a guide sliding shoe (2), a bearing seat (8) and a long shaft (7), wherein the protective cover (1) is provided with a boss (1a) for supporting the guide sliding shoe (2); the boss (1a) is arc-shaped, and an arc gap faces downwards; the guide sliding shoe (2) is provided with a ring-shaped supporting ring (2a) which is hung and sleeves the boss (1); the boss (1a) is used as a rotary shaft of the guide sliding shoe and enables the guide sliding shoe to rotate flexibly by + / -5-10 degrees along the circumferential direction; and a gap for axial jumping of the guide sliding shoe (2) is arranged between the protective cover (1) and the bearing seat (8).

Description

technical field [0001] The invention relates to a thin coal seam shearer traveling device, in particular to a thin coal seam shearer reverse buckle traveling device, which belongs to the technical field of coal shearer traveling devices. Background technique [0002] The traveling device of the thin coal seam shearer is composed of traveling wheels, long spline shafts, bearings, bearing housings and guide shoes. The long spline shaft utilizes the external splines at both ends to mesh with the internal splines of the planetary carrier and the traveling wheels respectively, so as to transmit power to the traveling wheels. [0003] When the traveling wheels get the power transmitted from the traction motor, they mesh with the rack on the pin row of the scraper conveyor to realize walking on the scraper conveyor. At the same time, the left and right guide shoes on the road wheel assembly and the two support shoes on the side of the coal wall support the weight of the shearer, a...
